How to Configure a Comcast Modem

After a Comcast representative sets up cable service at your home, use the items he gives you, including the Ethernet cable, USB cable and installation CD, to make your computer Comcast-compatible. It may take some time to set up all the components, however, so set aside an hour or two for the modem setup.

Modem Setup

Step

Connect one end of the cable to a cable outlet. Connect the other end to the cable port, located in the back of the Comcast modem. Twist the end around until it is completely tight.

Step

Plug the power cord into an electrical outlet. Plug the other end into the port, located in the back of the modem. If the modem has a power button, press it.

Step

Plug the end of the Ethernet cable into the Ethernet port, located in the back of the Comcast modem. Plug the other end into the Ethernet port in the processor, located in the back of the computer near the USB ports.

Step

Insert the Ethernet installation CD. Follow the instructions on the CD to install the Ethernet's driver. Exit the program after installation.

Step

Plug the square-shaped end of the USB adapter into the USB port in the back of the Comcast modem. Plug the rectangular end of the USB adapter into an open USB port in the computer.

Installation CD

Step

Insert the Comcast Cable Modem Installation CD. A pop-up installation screen will launch. Press "Next" and answer "Yes" to any questions about the installation process.

Step

At the license agreement screen, select "Accept" at the bottom of the screen. Click "Next."

Step

On the next screen, type in any name in the "Username" text box. Enter any password in the "Password" text box. Click "Next."

The installation will begin. If it finishes, click "Finish." If it says it failed, exit the program, restart it and go through the steps again. If it is still unable to start the installation, call Comcast's technical support for additional assistance.
